' Another objec't vision of an improved construction of this charactenprovided with improved means for if securing the parts in place.

the invention is the pro- Otherobjects will appear hereinafter. Theinvention consists in the combinations and arrangements of partshereinafter described and claimed.

The invention will be best understood by reference to the accompanyingdrawing forming apart of the specification and in which Fig. 1 is aperspective view of a cultivator embodylng the invention, i

Fig. 4: asimilar view taken substantially Fig. 5 a perspective view ofone end of a plurality of cultivator blades employed in theconstruction.

The preferred 1 2, adaptably arranged, as indicated, to constitute themain supporting framework of a rotary cultivating implement, "as shown.

i The endjdiscs and 11 are provided respectively with peripheral notches13 and 14 oppositely inclined with reference to each 1 planes other, andthe central. intermediate disc 12 a is provided with corresponding,alternately arranged, oppositely inclined slots 13' and 1 1, the slots13 being arranged inthe same as the slots 13'and the slots 14being rarranged in the same planes as theslots lllr 50 Annular securing ribs 15are arranged, asv

I form of construction, as illustrated in the drawing, comprises two enddiscs 10 and 11 and an intermediate disc support a draft bar a 10 and 11and on the opposite faces of the intermediate disc 12. Theslots "arethus arranged in the same planes so asto accommodate and receive theends of cultivator "blades of the cultivator blades 16-17 isprovidedneachi end; with a notch18a'nd a co-operatlng'securing tongue 19,;thenotch 18 being adapted and arranged to fit overthe correshown, ontheinner faces of the end. discs 16 and 17-, which will thus be arrangedin radially disposed, oppositelyinclinedrelavrtionshipiwith each other,as shown. Each 1 spending securingribtlli andthe tongue 19 being adaptedand arranged to engage under sa d rib, as 1nd1cated,jthereby securing tand lockingeach of said blades in place.

By this arrangement, when the ends) of the! blades 16 and 17 are thusplaced in the gaged under the corresponding securing. rib

15 a rigid eonnectionis eiiected whichserves to mount the blades '16 and17- in oppositely inclined relationship to eachother and also rigidlysecures the discs 10, 11 and12 in 1 place.

tivator arrangement upon the central truntion illustrated in Asupporting .bail 24; is also mounted onthe inclining the adjacent setsof cultivator blades 16 and 17 any lateral reaction resulting from theiruse will be counteracted and the central intermediate disc 12 will berigidly and firmly locked and held in place.

The specific form and arrangement of parts is a simple and effective onefor the purpose.

lVhile I have illustrated and described the preferred form ofconstruction for carrying the invention into eiiect, this is capable ofvariation and modification without departing from the spirit of theinvention. I therefore do not wish to be limited to the precise detailsdisclosed, but would desire to avail myself of the various variationsand modifications as fall within the scope of the appended claims.

Having thus fully described my invention, What I claim as-neW and desireto secure by Letters Patent is:

1. A rotary member for cultivators comprising end discs and anintermeoiate disc. said end discs being provided with oppositelyinclined slots in their peripheries and said intermediate disc withalternating oppositely inclined co-operatin slots in its periphery: andcultivator blades positioned in said slots.

2. A rotary member for cultivator-s com prising end discs and anintermediate d sc, said end discs being provided with oppositelyinclined slots in their peripheries and said intermediate disc withalternating oppositely inclined co-operating slots in its periphery;'

securing ribs on the inner face of said end discs and on both faces ofsaid intermediate disc; and cultivator blades positioned in said slots,each blade being provided at each end with a notch and locking tongue tofit over and engage the corresponding locking rib.

A rotary member for cultivators comprising end discs and an intermediatedisc, said end discs being provided with oppos inclined slots in theirperipheries and intermediate disc with alternating positely inclinedco-operatim periphery; securing ribs on the inner face of said end discsand on both faces of said intermediate disc; and cultivator bladespositioned in said slots, each blade being provided at each end with anotch and locking tongue to fit over and engage the correspondinglocking; rib; a central trunnion v bolt member extending centrallythrough all the said discs; and separate scouring bolts attaching eachdisc with its adjacent disc.

In. Witness whereof, I have hereunto set my hand this 14 day of March,1929.

JOHN F. ZEILINGER.
